Resin Buying Strategies - September 2010: Prices May Stabilize… Briefly
Prices of commodity resins, except for polypropylene, fell a bit more last month.
Prices of commodity resins, except for polypropylene, fell a bit more last month. But they may be bottoming out. Both PE and PP suppliers have price hikes on the table, although they may be delayed, say resin purchasing consultants at Resin Technology, Inc. (RTi) in Fort Worth, Texas. Here’s more of what RTi experts foresee.
PE PRICES FLAT OR LOWER
Polyethylene prices in July dropped another 2¢/lb for LLDPE and HDPE and stayed flat for LDPE. Tight supplier inventories appeared to halt further price erosion in August, and most major suppliers issued a 5¢ across-the-board increase for Sept.1. The move appears to have been initiated by Dow, which originally announced a 4¢ hike for Aug. 1. Meanwhile, the London Metal Exchange (LME) North American short-term futures contract for butene LLDPE film-grade in August was 51¢/lb, up from 48¢ in July. July PE prices in the secondary market for off-grade material moved up 1¢ to 2¢.
PE suppliers have been scaling back plant operating rates and some have delayed restarting idle plants. Their inventories dropped by an average of six days. LDPE availability continues to be tight here and in Europe, but Asia is beginning to see some relief, which is expected to reduce U.S. exports.
There’s no upward pressure from the monomer side. Spot ethylene prices averaged 31.8¢/lb in July, down about 6.5¢ from June. June contract prices were 5.25¢ lower at 39.5¢/lb and were expected to hold even in July.
Outlook & Suggested Action Strategies
30-60 Day: Buy as needed. For the remainder of the third quarter, a further increase in exports is possible, which will bolster suppliers’ attempts to raise prices.
PP PRICES STABLE FOR NOW
Polypropylene prices were flat in July, as in June, following the trend in propylene monomer contract prices, which remained at 55.5¢/lb. PP suppliers issued price hikes of 3¢ to 5¢ for Aug. 1, but they had no effect by mid-month. The LME short-term futures contract in August for g-p injection-grade homopolymer was 67.8¢/lb, up sharply from 58¢ in July.
Spot PP prices increased by 2¢ to 5¢ from June levels. The spread between spot and contract resin tabs disappeared and, in some cases, spot tabs rose above contracts. Spot prices were expected to move up by the end of August in light of pending price hikes.
PP secondary markets remained tight through July and August. Continued strong demand into the third quarter reduced supplier inventories to 31.9 days from 36.1 days. This tightness bolstered suppliers’ decision to issue price hikes.
Market conditions do not appear to support a rise in August monomer contract prices, despite proposals for increases of 2.5¢ to 3¢/lb. RTi expected August monomer contracts to hold even or rise no more than a penny or two.
Outlook & Suggested Action Strategies
30-60 Day: RTi thinks it will be very difficult for suppliers to raise PP prices without the support of higher monomer costs. RTi does not see any indicators of another run of PP price hikes on the horizon. Rather, price stability appears more likely, barring unforeseen events or monomer supply disruptions.
PS PRICES LOWER
Polystyrene prices dropped another 3¢ to 5¢ in July, following an average decrease of 4¢ in June. Another reduction of 2¢ to 3¢ is possible, though suppliers are fighting hard to hold onto their profit margins. Decreasing feedstock costs and growing resin inventories are driving lower PS prices.
Spot prices fell to about 60¢/lb for generic GPPS and 67-70¢/lb for HIPS. EPS prices dropped an average of 3¢ to 4¢ in July and there was potential for further decreases last month. Also, competition from EPS imports has returned, with prices FOB Northern Asia as low as 53¢/lb.
PS suppliers’ inventories remained flat at about 22 days—below the normal 25-day level—for most of the year. Resin plant operating rates were at 77% of capacity and EPS operating rates at 80%. Demand rates fell slightly for PS and rose sharply for EPS.
June styrene monomer contract prices dropped 9.25¢ to 58.25¢/lb and were expected to settle slightly lower for July. Spot monomer was trading near 45¢ in July and 1¢ to 2¢ higher in August.
selective-grinding and dry-sortation process
July butadiene contracts settled 2¢ higher, which affects HIPS. Imports have helped ease the supply tightness. Still, prices will stay high through this month.
Outlook & Suggested Strategies
30-60 Day: Further drops in PS prices are expected in August/September. Explore various supply options, including imports. Continue to buy as needed but “keep an eye on the weather.” Evaluate your purchasing strategy for the fourth quarter, as price increases are possible.
PVC PRICES LOWER
PVC prices sank another 1¢ to 2¢/lb in July, following a 3-4¢ drop in June. Falling ethylene monomer prices have played a key role. PVC suppliers enjoyed lower-cost ethylene in the second quarter and into the third. Chlorine prices, which had been low, are starting to rise, adding 0.5¢ to 1¢/lb to the cost of making PVC.
PVC plant operating rates trended downward in June/July after having held around 90% through the first half. Plants were running at 88% of capacity, with demand rates slipping to 84%. Suppliers built up stock in advance of an anticipated active hurricane season. As a result, their inventories grew by over 40% in the second quarter. Shintech is starting up its long-awaited second-phase expansion of 660 million lb, which will affect operating rates.
Outlook & Suggested Strategies
30-60 Day: Lower ethylene costs, reduced exports, and higher supplier inventories contributed to further resin price decreases in July/August. To minimize your resin costs in August/September, you can use the leverage of higher supplier inventories as the hurricane season wanes (assuming no major storms actually develop). Some rebound in PVC demand is possible through this month, and prices are expected to be flat or rise as a housing recovery resumes or exports rebound as the U.S. dollar weakens. Buy as needed.
